This study was conducted to determine the change of growth pattern of Chinese Yam (Dioscorea opposita Thunb.) affected by the continuous cultivation for three years from 2008 to 2010. The results obtained are as follows. Top growth of Chinese Yam was well-developed at 2nd and 3rd years rather than 1st year as cultivated year goes by. Dry weight of leaves and stems was higher in 52% at 2nd year and 106% at 3rd year compared to 1st year, respectively. The weight of bulbil of Chinese Yam was highest at 2nd year cultivation with 500g/(3.7 times) following 3rd year with 430g/(2.7 times) and 1st year with 157g/, respectively.
